L78 Oil Pressure switch reducers

[Unreal]

I guess I should have read more carefully. I think all the connectors are NPT, so I'll bet you can find them at your local ACE. They have a whole display of brass fittings in the plumbing area.

My set up is idiot lights, not gages, but I'm almost positive my sender fits directly into the elbow, without the reducers. Not saying that is correct, just that I'm not using reducers.

Unreal I appreciate your response's. I feel GM did not need to add all of these myself. I would rather have the sending unit go directly into the the 45 degree elbow. As I stated earlier the parts are the same if you have warning lights or gauges. I was wondering if they made the 45 degree (repro) to do away with these but would accept a larger threaded sending units. My 1969 and 1970 assembly manuals both show these, I may take your advice and see what ACE has to offer. Thanks

I have gauges in my 69 L-78 ElCamino, and there are no reducers. The sender screws directly into the 45 elbow. My 68 has reducers, but thats because the factory oil gauge is mechanical. I got those reducers at NAPA. The store by me has a big drawer unit full of fittings.
